First of all, the way arrests are being done right now, they are not going to tell you that you are being arrested because you peacefully participated in a protest. They are going to tell you that you have breached the national security law based on treason, sedition and so on. The charge itself is not peaceful protest; the charge is treason or sedition.
I think we can go beneath that to understand the conduct leading up to the charge, but rather than doing that and relying on the individual officer's interpretation of the facts and the law, we should look south of the border, as an example. I can't remember whether it's the U.S. Congress or Senate, but I believe they have basically stated that anyone charged with a criminal offence because of their peaceful participation in the protests in Hong Kong would not be barred from entering the U.S.
We can work something out that is similar to that requirement so we don't have to rely on individual CBSA officers, particularly in light of the fact that CBSA has recently tried to make the case for giving itself more power, as opposed to the immigration division, to decide who is criminally admissible and who is not.
